Gots to sign up first. The step by step is pretty explanatory, it tells you in detail pretty well in the different price options. I some things i did the cheaper options and others i did the more expensive, it just depends on the thoroughness you want them to do and how much help you think you'll need from them. I tried making it as cheap as possible since I'm doing 3 different names and possibly a 4th. They have people to call during business hours if you have any questions. Google the shit out of your idea before paying anything though. You don't want a similar name or idea out there already or it will make the tradmarking much more drug out and could result in wasting that money. Im having this issue with one of mine, and unfortunately it's the one i really wanted the most. It's going to be fought in court
